For Rosa Barba, cinema “allows time and space to vibrate, collapse, overlap, and extend.” Barba’s conceptual explorations of film probe historical records, personal narratives, and the sensory experience of celluloid, often by documenting natural landscapes and human-made changes to the environment. This installation spans 15 years of Barba’s work, featuring film, kinetic sculpture, and sound. A n

This thesis investigates the spectral properties of magnetic and nonmagnetic Schrödinger operators, which haveapplications in the distribution of superconductivity in type II superconductors and wave theory. The thesis beginswith an introduction to the main results in the field, giving a more detailed presentation for clarity. Next, we focuson the original research articles conducted by the author

This paper assesses the communication and the use of climate scenarios at the science–science and science–policy interface in Finland, Sweden and Norway. It is based on document analysis and stakeholder questionnaires. The questionnaires targeted three stakeholder groups, all engaged in the communication and the use of climate scenario information: climate scenario producers; impact, adaptation an

A physical lake model was employed to obtain a basis of discussing the impact of climate variability and climate change on the ecology of Lake Erken, Sweden. The validity of this approach was tested by running the PROBE-lake model for a 30-year period (STD) with observed meteorological data. The lake is adequately modelled, as seen in the comparison with actual lake observations. The validated lak

The increasing global demand for food will be met chiefly by increased intensification of production. For crops, this will be achieved largely by increased yields per area with a smaller contribution from an increased number of crops grown in a seasonal cycle. Production systems show a spectrum of intensification practices characterised by varying methods of site preparation and pest control, and

Rosa Barba's exhibition Meaning Distances opens this year's 25 FPS Festival at the Museum of Contemporary Art in Zagreb, bringing together a selection of sculptural film works. Barba’s conceptual explorations of film probe historical records, personal narratives, and the sensory experience of cinema and sound, often by recording natural landscapes and human-made changes to the environment.

A mid career retrospective exhibition celebrating the work of artist and filmmaker Rosa Barba, whose practice destabilses the conceptual terms of cinematic space.

Wind turbines are important for achieving renewable energy goals, but present a considerable threat to wildlife, especially birds and bats. This study reports 41 confirmed collisions of GPS-tracked Red Kites (Milvus milvus) with wind turbines across Europe (2017–2024). We compared environmental and turbine-specific factors during collisions and non-collision movements within 500 m of turbines. Col

Four downscaling experiments of regional climate change for the Nordic countries have been conducted with three different regional climate models (RCMs). A short synthesis of the outcome of the suite of experiments is presented as an ensemble, reflecting the different driving atmosphere-ocean general circulation model (AOGCM) conditions, RCM model resolution and domain size, and choice of emission

The Swedish regional climate modelling programme, SWECLIM, started in 1997 with the main goal being to produce regional climate change scenarios over the Nordic area on a time scale of 50 to 100 yr. An additional goal is to produce water resources scenarios with a focus on hydropower production, dam safety, water supply and environmental aspects of water resources. The scenarios are produced by a

Two 2 x 10-year climate change experiments made with the Rossby Centre regional Atmospheric climate model (RCA) are reported. These two experiments are driven by boundary data from two global climate change simulations, one made with HadCM2 and the other with ECHAM4/OPYC3, in which the global mean warning is virtually the same, 2.6°C. The changes in mean temperature and precipitation show similari

This work presents a regional climate model, the Rossby Centre regional Atmospheric model (RCA1), recently developed from the High Resolution Limited Area Model (HIRLAM). The changes in the HIRLAM parametrizations, necessary for climate-length integrations, are described. A regional Baltic Sea ocean model and a modeling system for the Nordic inland lake systems have been coupled with RCA1. The cou

The chemically induced ozone loss inside the Arctic vortex during the winter 1994/95 has been quantified by coordinated launches of over 1000 ozonesondes from 35 stations within the Match 94/95 campaign. Trajectory calculations, which allow diabatic heating or cooling, were used to trigger the balloon launches so that the ozone concentrations in a large number of air parcels are each measured twic

Microbial contamination in coastal environments and groundwater is explored within this thesis, focusing onfecal contamination from anthropogenic sources and microbial community dynamics. The spread andpersistence of microbial contaminants in complex aquatic environments with multiple intermittent and pointsources of contamination, was studied in order to lay a groundwork for developing more robus

The paper presents a new global modeling tool, Stratospheric Chemical Transport Model 2. It has been developed for effective three-dimensional multiyear stratospheric chemistry studies, featuring an extensive chemistry scheme, heterogeneous processing on sulfate aerosols, and some polar stratospheric cloud processes. The transport algorithm maintains sub-grid-scale distributions and connects verti

The total ozone reduction in the Arctic during the winters of 1993/94 acid 1994/95 has been evaluated using the ground-based total ozone measurements of five SAOZ spectrometers distributed in the Arctic and from number density profiles of a balloon-borne version of the instrument. The ozone change resulting from transport has been removed using a 3D Chemistry Transport Model (CTM) run without chem

Assessments of the possible future climate change, driven by anthropogenic emissions of greenhouse gases, are made with global climate models. These describe the large-scale features rather than regional details of climate, such as variations due to mountains, lakes, and inland oceans. Regional climate modelling improves the details in climate projections. Examples for the Nordic region illustrate

Polar stratospheric clouds (PSC) were observed with the multi-wavelength lidar of the MOANA project (Modelling and Observations of Aerosols in the Northern Atmosphere) during SESAME (Second European Stratospheric Arctic and Mid-latitude Experiment). The physical state, liquid or solid, of the cloud particles can be inferred from the lidar data. Using isentropic back-trajectories to obtain the ther
